Title: Jet type soldering device
Inventor: ABE MASAHIRO
IPC: H05K3/34
Filed: 1990-01-20
Abstract: PURPOSE:To prevent the quality deterioration of soldering by displaying an identification mark showing a kind on a substrate, connecting a discriminating device to a sensor to read the mark, connecting a controller to move substrate warp preventing bars to the discriminating device and sliding the substrate on the preventing bars to perform soldering. CONSTITUTION:The sensor 6 reads the identification mark displayed on the substrate 3 at the upstream side of a moving path of the substrate 3 and the kind of the substrate 3 is discriminated by the discriminating device 7 connected to the sensor 6. The substrate warp preventing bars 4 are moved automatically according to the kind of the substrate by the controller 8 connected to the discriminating device 7. In the state with a solder undeposited part supported by the substrate warp preventing bars 4, the substrate slides on the surface of molten solder jetting in a solder dip vessel 2 and solder is deposited on a desired part of the substrate rear 3a. Consequently, since the substrate warp preventing bars 4 move automatically according to the kind of the substrate, a changeover mistake can be obviated and the quality deterioration of soldering can be prevented.

IPC: G02F1/133
Filed: 1986-01-22
Abstract: PURPOSE:To reduce the power consumption of a liquid-crystal panel driving circuit and miniaturize the device, by providing low-pass filters having different delay times before three sequences of video signal lines. CONSTITUTION:Three primary color signals impressed upon video signal input terminals 101-103 are supplied to sample holding circuit groups 114-116 through low-pass filters 104-109.

Title: Image signal processing unit
Inventor: NAKAJIMA MITSUO
IPC: H04N7/015
Filed: 1995-01-27
Abstract: PURPOSE: To prevent the deviation in the image of a gravity position owing to variable processing in one frame period by using a motion reverse correction circuit to correct a received image signal. CONSTITUTION: An image signal outputted from a motion reverse correction circuit 5 is written sequentially in field delay circuits 6a, 6b. In this case when a signal inverting a vertical synchronizing signal is given as a clock signal for a latch circuit 7 from a clock signal input terminal 7, the received motion vector signal is delayed by one field and the result is obtained at an output of the latch circuit 7 and fed to the field delay circuits 6a, 6b. Thus, the field image signal corrected by the motion reverse correction circuit 5 according to a motion vector signal for a prescribed time and written in the field delay circuit 6a is subjected to motion correction by the motion vector signal and outputted after 1 field and -3H. That is, the processing without position deviation is attained by the control of forward and reverse motion correction with the same motion vector signal.

Title: Recording device of optical information
Inventor: HASHIMOTO NORIO
IPC: G11B7/12
Filed: 1983-01-28
Abstract: PURPOSE:To write and read out information signals without disturbance by using an optical system provided with a laser light source emitting laser light including an information signal and another laser light source compensating the output of the laser light including the information signal. CONSTITUTION:Laser light emitted from a main light source LD1 is reflected and diffracted on a disk surface 6 and is passed through a focus lens 5 and a 1/4 wavelength plate 4 again. The laser light is converted into counterclockwise circular polarization by the reflection on the disk surface 6 and then converted into straight polarization rectangular to the incident direction by the action of the 1/4 wavelength plate 4. Thus, the laser light is guided to a detector 7 through a beam splitter 3 and photoelectrically converted into an electric signal. In the same manner as the laser light from the main light source LD1, laser light from an auxiliary light source LD2 is reflected in the direction of the detector 7 by the beam splitter 3. However, an angle made by the laser light from the auxiliary light source LD2 and the laser light from the main light source LD1 is previously set up to theta to prevent the laser light from the LD2 from incidence into the detector 7, so that the information signal detected by the detector 7 is not disturbed.

Title: Printing method for cream solder
Inventor: MIIKE KOICHI
IPC: H05K3/12
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To fill even an elongated rectangular opening in a mask sufficiently with cream solder by preventing a squeegee from sliding in parallel with the longitudinal direction of each opening of mask. SOLUTION: Sliding direction of a squeegee 5 is set not in parallel with the longitudinal direction of each opening 42H, 42V. Consequently, even if a cream solder 22H, 22V filling an opening begins to be entrained by the squeegee 5, it is scraped from the squeegee 5 by the circumferential fringe of opening 42H, 42V, i.e., the sides parallel with the longitudinal direction, and thereby the cream solder 22H, 22V is prevented from being carried to the outside of opening. Consequently, the cream solder 22H, 22V can be printed with constant thickness on a printed wiring board 3 using a squeegee 5.

Title: Axial-flow impeller
Inventor: SUGA MASAYUKI
IPC: F04D29/34
Filed: 1983-01-31
Abstract: PURPOSE:To improve efficiency of an axial-flow impeller and reduce its noise, by arranging the leading edge external contour part of a boss plate approximately to the center of rotation from its trailing edge external contour part as viewed in the direction of rotation of the axial-flow impeller so as to decrease a region of turbulent air flow spreading on a fan blade. CONSTITUTION:A turning locus surface generated at rotation of a boss plate 2 is decreased by arranging a leading edge external contour part P1 to the center side of rotation from a trailing edge external contour part P2 of the boss plate 2. While a turning locus surface generated at rotation of a sloped surface 1J of a fan blade 1 is moved to the internal diametric side by arranging a leading edge part 1E to the center side of rotation from a trailing edge part 1D of the sloped surface 1J of the fan blade 1. Accordingly, a region influenced by a turbulent air flow is decreased generating less resistance against air flowing through a surface of the fan blade 1, as a result the total pressure efficiency is improved. While a noise is also reduced by a similar reason.

IPC: G03C11/24
Filed: 1980-02-07
Abstract: PURPOSE:To improve pattern-forming precision, by forming a layer of water-soluble high-molecular substance between a substrate and a resist layer and forming a pattern identically with the resist. CONSTITUTION:A layer of water-soluble high-molecular substance, polyvinyl alcohol for instance, and a resist layer 4 are stacked on an SiO2 film 2 on an Si substrate 1. After an application of electron beam irradiation and developing to form a pattern 40, an ooze 41 sticks to the bottom. Then the layer 3 is developed by water to form a pattern 30 with the resist 40 as a mask. The ooze 41 is attached to the side wall of the pattern 30. Then the SiO2 film 2 is etched to form a pattern 20 employing such a dry method as an ion etching. Lastly by removing the pattern 30 by water, the desired pattern is obtained. With the water-soluble high-molecular substance layer formed identically with the pattern on the resist, the ooze at the bottom of the resist falls to the side wall of the layer of water-soluble high-molecular substance, resulting in the formation of ultra-fine patterns.
